    In 10 years Little Britain is bankrupt and will sell the new build carriers to Brazil. 😎

    Problem is reaction time. There are a few seconds to react. And if one does not destroy the warhead of the missile, it has enough kinetic energy to reach the ship and impact, despite wrecked missile.

    France is the last to get the Meteor. Some years ago there were guided flights of Meteor on Gripen and Eurofighter. The program was stretched because Europe is not in danger and not short of A2A missiles.

    Oh…
    Supporters of terrorists are fighting against terrorists… LOL…

    Oh wait! Terrorists or freedom fighters? Who knows… Today you can name whatever one likes.

    Su-33 has 3000 km flight range with 4 missiles, same as MiG-29K’s FERRY range. Su-33’s central station is wet. Only reason it doesn’t carry an 3000l EFT is no body considered the need of a one. As for ASMs, Su-33 could carry 1x4500kg Kh-41 but not 4x520kg Kh-35s, RIGHT!! Speaking of airframe limitations, Su-33 has 8 pylons capable of holding Kh-35; it doesn’t have wiring, so Su-33 cannot use them, but that doesn’t mean J-15 will not too.

    AFAIK Su-33 can start from carrier with half internal fuel and weapons, or full internal fuel and no weapons. That’s the reason why Russia turns to the smaller MiG. Su-33 is too heavy to exploit the full range of the aircraft with ski jump. The same problem should have the Chinese with their J-15.

    I do not understand the intention of this thread. It is not possible to compare the aircrafts by their losses or their victories.

    How would they perform this in time of war when Italy is themselves heavily involved and under bombing?

    A long loiter aircraft is OK. But one does not need simultaneously targeting. With long loiter one has the time to pick out one target after the other. Well, as long as the IS do not have MANPADS one can take every cheap and cost efficient aircraft for that job with the adequate loiter time, even a Cessna. IMHO fast movers are a waste of money for such jobs.

    May be something like AC-130 would be more cost efficient, with a Derringer Door on the ramp. Guns and small missiles are more cost efficient than expensive big missiles. The US could hunt for pick-up convoys like in the 60ies trucks in Laos. In the desert and with modern surveillance systems it should be no problem.

    Exactly. The only objective results are the 172 J-11Bs and 344 WS-10As powering them.

    Views on quality controls are exactly that — views or subjective opinions. If there were major issues we would never see WS-10A powering 172 (and counting) heavy fighters.

    I think the issue is not quality control in the production line. The issues are the problems in developing new engines, new technologies, new alloys.

    In the first generation of “stealth” that may have been true. Newer fighters designed for LO use the fuel as a heat dump, comms/datalinks that are directed (MADL) etc., LPI radar that jumps frequencies, and passive detection that was not possible with the first generation of Low Observable fighters. In theory, engineers have tried to solve the problems that you have stated, to what degree they have been successful is a matter of conjecture and not likely to be open source information.

    You can not fool physics. Higher speed means friction and friction means heat. Heat must be discharged somewhere. If you keep the heat inside the whole aircraft will radiate heat or it will overheat with all it’s high tech inside. This is insane for modern aircrafts. This means you have to get rid of the heat and this can be gathered by IR-sensors. Nothing radiating is invisible. Even LPI radar you can spot with modern latest technology and sensitive broad band ESM gear. If your opponent knows you are there, but he doesn’t know where, he can take adequate measures to spot you. For example switch on bistatic/multistatic radars, long wavelength radars and EO sensors. IMHO even today a real stealth aircraft is an absolute silence aircraft with no radiations and no heat footprint.

    it true that high speed is lot more useful for stealth aircraft than a non stealth one
    but it may take alot of time to turn , depend on speed ( if iam not wrong at mach 2 fighter like F-14 and Mig-31 have turn radius about 40-60 km and remember they are optimum to operate at high speed , they can turn better at mach 2 than most fighter ) , not to mention , it really hard to avoid pop up threat when you flying fast

    No. High speed is not useful for stealth aircraft. Speed means warm-up of the surfaces and that means stealth is useless because the aircraft can be spotted by IIR-sensors. The hotter the surfaces (the higher the speed) the longer the range it can be spotted by IIR-sensors.

    A stealth fighter is stealth when it doses not emit any radiation. No radar, no ECM, no heat radiation, no communication…

    I can not understand why there are two towers. Every nation is building aircraft carriers with one tower only and they get smaller and smaller (Ford class).
